Co-solvent compositions and methods for improved delivery of dantrolene therapeutic agents

ABSTRACT

The present invention provides for methods of using tert-butyl alcohol (TBA) co-solvent systems in the formulation and production of a pharmaceutical agent with low solubility. The present invention also provides for pharmaceutical compositions made using the novel co-solvent system. In one embodiment, the invention provides for a method of making dantrolene sodium (DS) formulation for intravenous use (DS-IV). This instantaneous reconstitution of the DS-IV product constitutes a significant improvement in the pharmacotherapy of patients undergoing malignant hyperthermia during surgery.
